Appendix 1 - Unpacking and Inspection
Inspect the outside of the shipping carton for damage. If damage is detected, contact
the carrier immediately. Remove the instrument from the shipping container. Be
careful not to discard any parts or supplies. Confirm that all items on the packing
list are present. Inspect all assemblies and components for damage. Save the original
packing carton. Carriers typically require proof of damage due to mishandling.

ment:

Conductivity, DO, and pH
values are effected by temper-
ature. If conductivity, DO,
and pH values are incorrect,
verify that the temperature
probe is working correctly.
If the temperature probe is
reporting incorrect values,
conductivity, DO mg/L, and
pH values are not reliable.

sation and conductivity -
